This invention relates to anchors for fastening bucks and the like intoplace, and with regard to certain more specific features to an anchor ofthe class described, adapted to be tightly imbedded in walls or thelike.

Among the several objects of the invention may be noted the provision ofan anchor adapted to be readily fastened to various sizes of objects tobe held, the provision of means for readily but permanently setting theanchor in a wall or the like, and the provision of a compact and simpledevice which is exceedingly easy to manufacture and to put into use.Other objects will be in part ob- 5 vious and in part pointed outhereinafter.

The invention accordingly comprises the elements and combination ofelements, features of construction, and arrangements of parts which willbe exemplified in the structure hereinafter described, and the scope ofthe application of which will be indicated in the following claims.

In the accompanying drawings in which are illustrated two of variouspossible embodiments of the invention,

Fig. 1 is a flat plan view, prior to bending, of one form of the anchor,to be referred to hereinafter as the single anchor;

Fig. 2 is a perspective view illustrating the application of the singleanchor;

Fig. 3 is a fiat plan view of another form of the anchor, to be referredto hereinafter as the double anchor, and shows how this double anchor isformed from a single strip of material;

Fig. 4 is a perspective view illustrating the application of the doubleanchor;

Fig. 5 is a fragmentary longitudinal section taken on the line 55 ofFig. 1, and illustrates certain embossed portions common to the twoforms of anchor;

Fig. 6 is a side elevation of a door buck in place, showing theapplication of either form of the anchor; and

Fig. 7 is a fragmentary perspective view showing a modification.

Similar reference characters indicate corresponding parts throughout theseveral views of the drawings.

Referring now more particularly to Fig.

1, there is illustrated a stamping, composed preferably of sheet metaland comprising a substantially flat holding plate or engaging element 1,at one end of which are formed sideward extensions 3. A pair of arms 5are angularly arranged with respect to the extensions 3.

The holding plate 1 is provided with a plurality of openings or tubularelements 7 which are embossed in such a manner that their peripheriesform protruding rims 9. It is evident from the drawings that the tubularelements have a greater axial length than the thickness of the platefrom which they are embossed. The edges of these rims are inherentlysomewhat sharp due to the embossing operation. The arms 5 are preferablyprovided with small openings 11 for accommodating nails or otherfasteners, the use of which is to be hereinafter described. Theseopenings 11 are not required if the anchor is made of material which isthin enough to permit of driving a nail directly therethrough.

It is evident that the single anchor may be cut with a single die andembossed at the same operation, thereby providing easy manufacture.

The purpose of the anchor is to hold door bucks 13 or the like (Fig. 6)in proper relationship with respect to awall 15 or the like. In order toapply an anchor of the type illustrated in Fig. 1, the arms 5 are bentdownwardly (preferably at right angles) along lines 17. The distancebetween the inner flat faces of the arms, after bending, is equal to thewidth of the leg of the buck to which the anchor is to be applied.

The lengths of the arms are greater than the thickness of the leg of thebuck to which the anchor is applied. The inner edges 19 of the legs ofthe buck are adapted to cross the arms at substantially a line X. Bythis means, end flaps 21 are provided which may be bent around theinside of the leg 13 when the anchor is applied.

The complete operation in setting a buck with this form of anchor is asfollows:

The buck is placed on the floor 22 as the wall 15 is built up. The wallmay comprise a brick, tile or any other masonry or other constructionwhich will accommodate the placement of the anchor in a soft materialwhich will later harden around said anchor. One particular andadvantageous form of material used at present comprises light weightblocks-which are used for partitions and the like where littlestructural strength is required and light weight is desirable. Theblocks are made of material that is soft enough to be readily indented.

The wall is built up around the buck 13 up to a predetermined level andmortar is used between the successive courses of'blocks. At saidpredetermined level an anchor (which already has its arms 5 bent atright angles With respect to the plate 1 and extensions 3) isslippedover the buck with said arms engaging'the sides of the buck leg 13.Before the holding plate 1 is lowered to the wall construction, a layerof mortar is applied on the last course of said wall construction. Theholding plate is then brought down so that the downwardly extendingembossed lips 9 are pressed'therein. The workman then taps or hammersthe holding plate with his trowel or other tool. If the blocks of thewall are made up of the relatively soft material above described, thenthe lips 9 will be pressed therein. If the blocks are made of hardermaterial, the mortar is depended upon to hold the anchor.

Next, a layer of mortar is applied above the anchor'and the next courseof building blocks applied. It may be seen from the above, that the lips9 provide a positive grip in the building blocks, and are furthermorekeyed by the action of the mortar which flows into the opening 7 fromabove and from below.

After this the lapping or flap portions 21 may be bent around the insideof the leg 13. Both the arms 5 and the lap portions 21 may now be nailedor otherwise fastened. It is to be understood that the material of whichthe anchors are made may vary in thickness and as a consequence theopenings 11 may sometimes be dispensed with, that is, when the materialis thin enough to drive the nail directly therethrough.

The application of an anchor may be repeated at optional intervals as awall is built up.

The single anchor may be made in various sizes to accommodate variousstandard sizes of bucks. However, some odd sizes of bucks areencountered for which the modified form of'double anchor is used, shownin Figs. 3 and 4. This modifiedform may also be applied to standardsizes of bucks.

Each double anchor comprises a pair of units 27'. Each unit 27 comprisesa holding plate 29from one side of which extendsan arm 31 adapted to bebent angularly with respect to the holding plate 29 along a line 33.

The elements 27 of the double anchor may be economically punched from astrip as illustrated in Fig. 3 by nesting the pattern. The holdingplates 29 are provided with openings 34 which are also embossed in themanner described for the openings 7 1n the above described form. Nailholes 35 are provided whenthematerialofthe anchor. is relatively thick.

For applying this double anchor, the wall Aftermortar is applied abovethe holding plates 29 and'the next course of building material applied,the lapping ends or flaps 39 of the arms 31. may be bent around the buckleg. The arms and flaps are then nailed as before. Itis evident from theabove that the double anchors may be applied to any width of buckbecause the relationship between the arms 31 of a pair is not fixed.

It is to be understood'that in either of the forms ofanchorybendingalong lines such as 17 and 33 may be accomplished at the time ofmanufacture or be left to be accomplishedby the workmena-t the time ofapplication of the anchor; Eitherprocess has its advantages.

\Vith regard to the double anchor modification, it should be noted thatright and left elements are required, so that after the elements 27 arepunched out of the material strip, one-half of'tliem should-be bent inone direction along their respective lines 33 and one-half. of themshould be bent in the opposite direction on their respective lines.Likewise the embossing forthe'openings 34 should preferably extend inthe direction that the respective arms 31 are bent.

It is to be understood that the. key openings such as '7 and 34 may beembossed upwardly or alternately upwardly and downwardly.

In Fig. 7 is illustrated a form of holding plate 4.1 to whichcorrugations 43 are applied instead of. embossed openings. This form. ofplate also provides an excellent grip'for the anchor where it isdesiredto have the mortar do all the gripping.

In view of the above,- it will be seen that the several objects of the;invention. are achieved and other advantageous results attained.

As many changes could bemade in carrying out the above constructionswithout departing from the scope ofthe invention, it is intended thatall matter contained in the above descriptionor shown in theaccompanying drawings shall be interpreted as illustrative and not in alimiting sense.

I claim:

1. An anchor of the class described comprising a holding plate, meansthereon for gripping said plate to the blocks comprising the courses ofa Wall, said means being also adapted to permit keying of the plate bythe mortar between said courses, sideWard extensions on the plateadapted to engage a buck, separate arms extending from said extensionsformed in a plane at right angles to said holding plate and extendedflaps on the arms adapted to be bent around the leg of a. buck as saidarms engage the sides of said leg.

2. An anchor of the class described comprising a holding plate, meansthereon for gripping said plate between the blocks comprising thecourses of a Wall, sideward eX- tensions joined to the plate andpositioned substantially at right angles thereto, the extensions havingextending arms adapted to engage a buck.
